“It has been a year since she disappeared, and it has been a terrible strain on the whole family,” he said.

But despite that, he is encouraged by the reward money offered by Mehta-Paul’s two brothers – $10,000 for information leading to an arrest, and another $10,000 for information leading to the discovery of her body.

Mehta-Paul was last seen on March 21, 2011, and did not show up for work at her eye clinic in Highland, Ind., the next day, despite having several appointments scheduled. She had left her office the day before and deposited money at a First Bank branch in Highland, but disappeared soon afterward.

Surveillance cameras caught the last known images of his ex-wife making a deposit at her bank in Highland, Ind. Police have said she got in her gold Toyota RAV4 and drove off, but never returned home and didn’t show up to work the next day.

Her son, Paresh Paul, was living with her in Munster, and was named a person of interest, but no one has been charged.

The family hopes the reward money will stir up more leads.

“I’m very optimistic that the reward will encourage someone to come forward with important information,” Daman Paul said.
